Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554030, here are decompositions:

17 + 31554013 = 31554030
19 + 31554011 = 31554030
37 + 31553993 = 31554030
43 + 31553987 = 31554030
47 + 31553983 = 31554030
127 + 31553903 = 31554030
163 + 31553867 = 31554030
197 + 31553833 = 31554030

Showing the first eight; more decompositions exist.
